Diamond Dallas Page wants a piece of the Roc.

The former pro wrestler has sued vaunted rapper and Def Jam label executive Jay-Z, claiming the Roc-A-Fella Records founder has been illegally using his trademark "diamond cutter" hand gesture. The suit was filed December 2 in US District Court in Los Angeles, accusing Jay-Z--real name Shawn Carter--of trademark and copyright infringement as well as misappropriation of the hand symbol.

Page is seeking an injunction to prevent Jay-Z from using the gesture, as well as unspecified monetary damages.

Although Page never officially copyrighted the gesture, which uses the index finger and thumb on each hand to make the shape of a diamond, he said he has the rights to its use since he's been using it since 1996.

Jay-Z has been using the symbol for years to represent his Roc-A-Fella Records, which he co-founded in 1995, including on the cover to the album Roc-La-Familia: The Dynasty.

Page's Monterey Park, California-based lawyer, George Gallegos, told MTV News that Diamond Dallas--real name Page Falkinberg--is suing the rapper to protect his livelihood.

"People would come up to him and ask him if he was letting Jay-Z use it or if he had licensed it to him," Gallegos said of the symbol. "People [would also] say he's using Jay-Z's sign."

Page sports the hand gesture on the cover of his new book, Yoga for Regular Guys: The Best Damn Workout on the Planet!.

Gallegos told MTV News that he first took the hand-gesture matter directly to Jay's lawyers, but they were not receptive.

"Jay-Z and Roc-A-Fella Records use this symbol to promote themselves, to promote their artists, to promote their music, and to promote their fan base," he said. "The way that it's being used by Jay-Z and Roc-A-Fella is taking value away from it and creating confusion upon the public."
